Web Extensions: duplicate bundles when importing the same file via `import` and `manifest.json` about parcel HOT 3 OPEN

I also tried using the same exact path in both, to no avail:

import appUrl from 'url:./index.html';

	"action": {
		"default_icon": "logo.png",
		"default_popup": "./index.html"
	},

from parcel.

Does new URL("index.html", import.meta.url) cause the same problem?

from parcel.

Yes. I also tried matching the exact string in both ways: index.html, ./index.html

from parcel.
